Quality Control

Our 1-Methylethane-1,2-Diyl Dipalmitate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, and we support compliance with relevant industry standards. Customized specifications and purity grades, including technical and refined grades, are available to meet specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to prevent degradation. Keep away from heat, sparks, and open flames. Ensure the storage area is free from strong oxidizing agents.
